[Bug 572951] [NEW] wake-up from suspend-to-RAM ends with blackscreen

[Tommy_CZ]

Public bug reported:

I upgraded to 10.04, I use suspend-to-RAM often on my HP 6735s laptop
but after wake-up, the screen is black now after upgrade. I mean the
brightness is on but the whole screen is back. Suspending to ram with
kernel 2.6.32-06 is sometimes OK, sometimes it does the same thing with
black screen.
